From Friday through Monday, July 13 to 16, Eastside Corridor Constructors (ECC) and the Washington State Department of Transportation (WSDOT) will close the SR 520 floating bridge and highway to demolish the 84th Avenue Northeast overpass, complete the demolition of the north abutment of the old 92nd Avenue overpass and complete other time-sensitive construction activities.
Here are the details of the closure:
- Date: July 13-16
- When:Beginning at 11 p.m. on Friday, all ramps, the floating bridge and highway will be closed. Everything will reopen by 5 a.m. Monday morning.
- Where: Both directions of SR 520 and all ramps between Montlake Boulevard and I-405, except for the eastbound entrance from 108th Avenue N.E.. SR 520 will remain open between Montlake Boulevard and I-5.
The demolition at 84th Avenue Northeast is scheduled to begin about 3 A.M. and take about 18 hours to complete. Crews there will use two excavators with concrete crushing jaws and a large jackhammer called a hoe ram, as well as loaders and trucks for hauling away rubble. The demolition of the abutment at 92nd Avenue will be done during the day on Saturday, July 14.
We’ll also be installing drainage culverts, repairing potholes, sweeping and performing other maintenance activities all along the corridor.
ECC and WSDOT thank you for your patience and help reducing backups during our previous weekend closures of the SR 520 floating bridge and highway, and we need your help again this month. With thousands of vehicles traveling this route on a typical weekend, we need drivers to take alternate routes, avoid the area unless you have to go to the Eastside or Seattle and plan for added travel time and delays. We also suggest using carpools and transit.
Please help spread the word about this closure and post to your websites, social media sites and blogs. This is one of several weekend closures of SR 520 this year, with the next one scheduled for the weekend of August 10-13 when we’ll demolish the crossing at Bellevue Way, and install another fish friendly culvert just east of there. Details will be posted on our website.
This work is part of the $306 million SR 520 Eastside Transit and HOV Project that will improve safety, access and reliability in the corridor when complete in 2013. If you’d like to see photos of the work crews accomplished during previous weekend closures please visit WSDOT’s flickr site
